f'pletely of the stone.

The invention contemplatestlie drawing down into xed position of thestone against a resilient member so that when the securing means maybedrawn up snugly, the stone will in turn be drawn down to a nal positionagainst that resilient means and be continued to be backed up thereby.

The primary advantage of the invention resides in the fact that breakageof the stone is reduced to a very low minimum, and moreover a tightnessof the mounting of the stone is preserved over practically the life ofthe ring. Also, by use of the invention in the factory stones arereadily mounted with a degree of speed, due to the fact that the stoneis not mounted against a solid, non-resilient base as has heretoforebeen the case.

The invention may be applied to various stone mountings including therecessed mounting, or these mounting-s wherein there is a bezel entirelyaround the periphery of the stone, the bezel being rolled or peened overafter the stone has been completely fixed in position.

Not only is the breakage of the stones reduced by use of the invention,but the Workman is able to mount the stone with perhaps less skill andwith more certainty of securing a rigid, tight mounting.

These and many other objects and advantages of the invention will becomeapparent to those versed in the art from the following description,which is made in reference to the accompanying drawing, in which Fig. 1is a view on an enlarged scale of a ring mounting in top plan;

Fig. 2 is a similar top plan View but with the stone and crest removed;Y

Fig. 3 is a view in section on the line 3-3 in Fig. l; and

Fig, 4 is a detail in section transversely of the mounting.

While the invention may be applied to a great range of styles ofmountings, it is herein shown as applied to a recess mounting. The shankIB is prepared in the usual manner With a central fiat area I I. A baseI2 is formed to have a central opening I3 therethrough herein shown asbeing rectangular. This base I2 is aflixed to the 1 claim. (elysa- 15)shank in the. usual and well known manner. Around the base opening I3,there is provided a ledge I4 entirely therearound. as the margin of theopening I3. There is placed within the ledge vI4 a spring member I6 in agenerally H-shape to rest on the iiat area II. This member I6 has aVtransverse width slightly less than the transverse Width ofv the openingI3, and is' provided with the pairs of legs Ii, i8, and I9, 2D on theopposite ends thereof. The overall length of the member I6 is less thanthat of theopening I3, and, moreover, this member I6 is arched in thatit is concave from the underside and convex from the upper side asindicated in Figs. 3 and 4. The member it is made out of any suitablematerial which will be spring-like in nature, such as bronze or aberyllium copper composition.

Then a stone I5 is placed over the spring member i6 and a metal crest 2lhaving two downturned posts 22 and 23 is brought over the stone I5, andthese posts 22 and 23 are inserted downwardly through the stone I5, thestone I5 being provided with apertures 30 and 3| therefor, so that theposts 22 and 23 will pass between the arms I1, I8 and I9, 20respectively, as indicated in Fig. 3. These posts may be solid ortubular as herein shown.

These posts 22, 23 have suilicient length to extend through and belowthe under side 32 of the shank I B, so that the extending ends of theseposts 22, 23 may be ared, spun, peened, or riveted over against theunder side 32 se as to draw down the crest 2l against the stone I5 andin turn to press it against the spring I6 to` compress the spring Itsomewhat but still have the spring I6 yieldingly space the under side ofthe stone I5 above the ledge I4. The thickness vertically of the springItis made to be such that when it is drawn down to that compression justindicated, it will preserve sucient curvature to space the stone abovethe ledge.

The stone is preferably beveled on each end as at 33 and 34 so that theupturned base ends 35 and 35 may be worked over these ends 33 and 34 ofthe stone I5 to complete the mounting to prevent play endwise of thebase. The stone I5 iits between the side walls 37 and 38 of the base.

Thus the stone I5 and its overlying crest 2l are very securely mountedon the shank IIB in a secure manner, and yet in a manner whereby thecentral area of the stone I5 is resiliently supported to be yieldinglyheld against possible fracture during the mounting operations as well asagainst breakage from accidental knocks when the ring is in use. Inactual practice, the clear- Without departing from the spirit of theinvern., tion, and I therefore do not desire mbe, limited,
